Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel surrounding rock deformation monitoring equipment, in particular to a cableway for a surrounding rock deformation monitoring terminal. Background Art
[0002] Tunnel surrounding rock deformation automatic deformation monitoring terminals are used to identify tunnel cross-section deformation. They are installed in unstable areas such as the tunnel face and primary support under construction. During blasting operations, they must be quickly disassembled to prevent damage from the blasting impact. Once blasting is complete and measurements can be taken, they must be quickly reassembled to resume measurement. Existing terminal installation structures typically fix the terminal to the tunnel, making it difficult to quickly install and remove, resulting in inconvenient use. Utility Model Content

[0010] Fixed plate;
[0011] a connecting plate, vertically connected to the middle of the fixing plate;
[0012] The raised portion is formed at the other end of the connecting plate relative to the end connected to the fixing plate.

[0015] Optionally, the cross-section of the raised portion is circular.
[0016] Optionally, the electric slider includes:
[0017] a slider having a notch and an inner hollow portion;
[0018] A pair of pulleys are symmetrically connected to the slider via a rotating shaft so that the slider is connected to the raised portion;
[0019] a rotating motor, built into the slider and connected to any of the rotating shafts;
[0020] The rotating motor controls the rotating shaft to rotate so that the pulley rotates and rolls relative to the raised portion, thereby driving the deformation monitoring terminal to move along the length direction of the T-shaped fixing frame.
[0021] Optionally, the size of the notch is slightly larger than the thickness of the connecting plate and smaller than the diameter of the protrusion.

[0029] Example: See Figure 1 FIG. 1 shows an embodiment of a cableway for a terminal for monitoring surrounding rock deformation, which includes a T-shaped fixing frame 12 that is detachably connected to a primary masonry surface 23 in a tunnel 2; and a raised portion 20 formed at one end of the T-shaped fixing frame 12 away from the primary masonry surface 23; when blasting is performed on the tunnel face 21, the electric slider 16 of the deformation monitoring terminal 111 slides along the length direction of the raised portion 20 and away from the tunnel face 21 to enter the next section of the raised portion 20, and can quickly disassemble and separate the front section of the T-shaped fixing frame 12 from the primary masonry surface 23.
[0030] In this embodiment, the T-shaped fixing frame 12 includes a fixing plate 13 ; a connecting plate 14 vertically connected to the middle of the fixing plate 13 ; and a raised portion 20 formed at the other end of the connecting plate 14 relative to the fixing plate 13 .
[0031] In this embodiment, the fixing plate 13 is fixed to the primary masonry surface 23 by fixing bolts 15 .
[0032] In this embodiment, the lengths of the fixing plate 13 , the connecting plate 14 and the raised portion 15 are consistent, and two adjacent T-shaped fixing frames 12 of different sections can be in close contact with each other.
[0033] In this embodiment, the cross section of the raised portion 20 is circular.
[0034] In this embodiment, the electric slider 16 includes a slider 17 having a notch 171 and an inner hollow portion 172; a pair of pulleys 18 symmetrically connected to the slider 17 via a rotating shaft 19, which connects the slider 17 to the raised portion 20; a rotary motor 110 built into the slider 17 and connected to any one of the rotating shafts 19; the rotary motor 110 controls the rotation of the rotating shaft 19 to rotate the pulley 18, causing it to roll relative to the raised portion 20 and drive the deformation monitoring terminal 111 to move along the length direction of the T-shaped fixing frame 12.
[0035] In this embodiment, the size of the notch 172 is slightly larger than the thickness of the connecting plate 14 and smaller than the diameter of the protrusion 20 .
[0036] In this embodiment, the shape of the wheel surface of the pulley 18 matches the structure of the raised portion 20 .
[0037] The following description will further explain the characteristics and functions of the present invention.
[0038] The cableway structure of this embodiment is mainly used when blasting is required at the tunnel face. The traditional installation method is not convenient for the rapid disassembly of the deformation monitoring terminal and is easily damaged by the impact of blasting. Therefore, a slide rail for the surrounding rock deformation monitoring terminal is proposed, including a T-shaped fixing frame 12 for installation on the initial masonry surface 23 in the tunnel. The T-shaped fixing frame 12 is fixed to the initial masonry surface 23 by fixing bolts 15. The T-shaped fixing frame 12 also includes a fixing plate 13 and a connecting plate 14. The fixing plate 13 is fixed to the initial masonry surface 23 by fixing bolts 15. The connecting plate 14 is vertically connected to the center of the fixing plate 13 to form a T-shaped structure with the fixing plate 13; the connecting plate 14 has a raised portion 20 formed on the end connected to the fixing plate 13.
[0039] A motorized slider 17 is mounted on top of the deformation monitoring terminal 111. This slider 17 has a hollow portion 171 and a notch 172. The notch 172 is slightly larger than the thickness of the connecting plate 14, and the space within the hollow portion 171 is larger than the raised portion 20. This allows the slider 17 to fit over the raised portion 20 of the T-shaped bracket 12. The T-shaped bracket 12 and the raised portion 20 form the cable 11, which in turn forms the cableway assembly 1 with the deformation monitoring terminal 111.
[0040] A pulley 18 is provided at two vertical positions, one above and one below, within the electric slider 17. The two pulleys 18 tightly engage the raised portion 20 at the upper and lower positions. The pulleys 18 are rotatably mounted within the electric slider 17 via a rotating shaft 19, and their rotation is controlled by a rotary motor 110. When the rotary motor 110 is activated, the pulleys 18 rotate via the rotating shaft 19, causing the pulleys 18 to roll relative to the raised portion 20 and move along the length of the cable 11.
[0041] The cableway of this embodiment can be disassembled and connected between multiple sections. Preferably, the fixing plate 13, the connecting plate 14 and the ends of the raised portion 20 are all smooth planar structures. Therefore, adjacent cables 11 can be seamlessly and portablely connected, thereby extending the sliding distance of the cableway to increase the monitoring and free sliding range of the deformation monitoring terminal 111.
[0042] During use, the fixing plate 13 of the T-shaped fixing frame 12 is fixed to the initial masonry surface 23 in the tunnel by fixing bolts 15, and then the electric slider 17 of the deformation monitoring terminal 111 is put on the raised portion 20. The rotation motor 110 is started to control the deformation monitoring terminal 111 to slide on the raised portion 20 (i.e., the cable 11).
[0043] When blasting occurs at the tunnel face 21, the deformation monitoring terminal 111 slides along the length of the raised portion 20 and away from the tunnel face 21, into the adjacent cable 11, thereby preventing damage to the monitoring equipment. Removing the fixing bolts 15 allows the T-shaped fixing frame 12 to be quickly separated from the primary masonry face 23. The T-shaped fixing frame 12 and the primary masonry face 23 can then be reattached using the fixing bolts 15 when needed.
[0044] To sum up, when a cableway is used for blasting at the tunnel face, the terminal for monitoring surrounding rock deformation of the utility model can automatically slide along the cableway and away from the tunnel face to prevent the monitoring instrument from being damaged by the blasting. At the same time, the cableway can increase the monitoring and free sliding range. The cableway can be recycled to save monitoring costs. The cableway can be used for the terminal for monitoring surrounding rock deformation in real time as needed to monitor the deformation of surrounding rock at any section.
[0045] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
